Couldn't Start Dropbox - permissions error.

[mgw]

I get this error msg on new MacBook pro. Just migrated over from iMac. I can see icon in tool bar, but Dropbox won't start. Help much appreciated.  Mitch

Hi there mgw, 

It appears that a specialist of our team will need to look into that as a follow up on this issue, since there are especific troubleshooting steps that need to be followed. 

It would be advisable that you write in to us at dropbox.com/support. Can you please do this and give me with the ticket number or reply to this post in order to proceed with that?

Looking forward to your reply! Thank you!

Kind Regards,
JaneA

Just wanted to let you now - the previous version 15.4.22 works like a charm again on my Snow Leopard iMac 😉
I assume the updates messes up!?

[Didier C.]

Yes, it does, and since we can't turn auto-updater off, we're essentially screwed...

[spike1911]

Nope - you can lock the Dropbox app in your Applications directory - seems to block the updater 😉

[Didier C.]

Yeah, I could do that, but for an app that loads on startup, in the background, it's not an ideal solution. Right now, I've resorted to saving my Dropbox folder in Google Drive (I know, I know...), so that it'll sync with the rest of the content there. I'll just have to sync both folders every once in a while, via Terminal if I have to.
